1.64 Ct. Spinel from Ceylon (Sri Lanka)

This transparent greenish blue spinel weighs 1.64 carats, and is fashioned into an elegant oval shape measuring 7.96 by 6.07 by 4.51 millimeters, yielding a length to width ratio of approximately 1.31, and a depth that equates to approximately sixty four percent of the average diameter. The gem has been cut as a mixed brilliant, integrating a brilliant style crown with a precision pavilion arrangement designed to optimize scintillation and color saturation. Face up the stone displays an intense color intensity, a saturated greenish blue hue that reads deep in ambient and incandescent light, while retaining lively flash and dispersion attributable to the brilliant facet pattern. Clarity is graded as very very slightly included when evaluated at eye level, indicating that the stone appears essentially eye clean, with only minute inclusions visible under strong magnification that do not detract from the overall transparency or light performance. The polish is excellent, the girdle has been finished to a professional standard to ensure secure setting, and there has been no enhancement, the stone being entirely natural in origin from Ceylon, Sri Lanka, a provenance noted for producing spinels with refined color and classic clarity.

From an optical and material perspective, spinel is an isotropic gem with optical characteristics that differ from pleochroic species, meaning this specimen presents its true greenish blue hue uniformly regardless of orientation, an advantage for consistency in jewelry designs. Typical refractive index values for spinel place it in a range that promotes strong brilliance for its density class, and its specific gravity and Mohs hardness near eight confer a durable yet brilliant gem that is well suited to daily wear when properly set. The mixed brilliant cut employed on this stone uses a strategically proportioned crown, with star and kite facets that enhance light capture, and a precisely faceted pavilion, which together produce a balance of return and dispersion while also intensifying perceived color. The cutting retains a balanced table and crown height proportion to the pavilion depth, which contributes to controlled windowing and maintains saturation at the table, so the face up presentation is uniformly lively without excessive dark areas. Because this oval presents a slightly elongated profile, it works exceptionally well in solitaire settings to visually lengthen the finger, and it also lends itself to halo or three stone designs that can amplify perceived size and color, while protective bezel settings are recommended for wearers seeking additional security due to the oval outline.

Craftsmanship on this piece reflects deliberate technical choices by the lapidary to harmonize color saturation with optical performance, a refinement we emphasize at The Natural Gemstone Company. The cutter has prioritized facet symmetry and proportionality, which is evident in the even luster across facets and the clean facet junctions that contribute to crisp scintillation. The mixed brilliant approach in an oval form requires careful attention to girdle thickness and pavilion termination to avoid light leakage and to prevent the formation of a boats eye or bow tie effect, and this gem shows minimal bow tie influence owing to its calculated profile and facet angles. The absence of enhancement affirms that the stone’s color and clarity are intrinsic, and its Ceylon origin situates it within a well documented geological context where spinel crystals often crystallize in high quality pockets, producing saturated blues and blues with green modifiers. For gem cutters and jewelers, the stone’s dimensions and proportions make it straightforward to set in custom designs without extensive reworking, preserving carat weight while allowing for precision seat cutting and bezel or prong work that protects the girdle and maintains the stone’s optical integrity.

Beyond its material and aesthetic attributes, this greenish blue spinel is traditionally ascribed a range of metaphysical and healing qualities that are of interest to collectors and those who incorporate gemstones into holistic practice. Historically, spinel has been viewed as a revitalizing stone, associated with renewal, increased energy, and restorative fortitude, and the presence of a green blue hue brings additional associations with the heart and throat energy centers, promoting harmonized emotional expression and clear communication. Practitioners who work with crystal energies often place emphasis on spinel for stress reduction and emotional recalibration, describing the stone as supportive for easing anxiety, cooling emotional reactivity, and facilitating a composed articulation of thoughts. The greenish component is linked to heart centered qualities such as compassion and healing, while the blue aspect resonates with aspects of mental clarity and verbal articulation, a combination that favors balanced empathy and truthful self expression. Many proponents recommend wearing such a stone as a ring or pendant to keep its influence proximal to the physical body, or using it in meditation and intention work to anchor resilience, boost confidence, and encourage the release of stagnant emotional patterns. These traditional attributions are part of a long cultural tapestry of gem lore and spiritual practice, and they should be considered as complementary perspectives rather than substitutes for professional medical or psychological care.

For connoisseurs and craftsmen seeking a natural, well proportioned, and technically superb example of Ceylon spinel, this 1.64 carat greenish blue oval embodies the critical balance of color intensity, optical performance, and durable material properties. Its mixed brilliant faceting maximizes brilliance and color retention, the clarity grade ensures a visually clean presentation, and the excellent polish enhances surface reflectivity and tactile quality. When acquired from The Natural Gemstone Company, clients can expect accurate documentation of origin and treatment status, careful handling, and the option for bespoke mounting recommendations that preserve the gem’s visual virtues and structural safety. Whether selected for a signature engagement piece, a fine bespoke commission, or as the centerpiece of a curated collection, this spinel presents a technically impressive and aesthetically compelling choice, combining measurable gemological parameters with enduring traditional appeal.
